My 7 y.o. granddaughter and 9 y.o. grandson enjoyed it in October ... we spent a couple of hours there ... I can't take much more than that due to the noise.
But with the new park passes I doubt I'll being willing to use one of my "plusses" to go to Disney Quest ... actually I doubt I'll buy a pass with any pluses at all ... we'll just skip the water parks and DQ ... in the past I've gotten the ultimate park hoppers and love being able to do a theme park in the morning, a water park in the early afternoon and then DQ in the late afternoon or early evening ... with the new passes that's just too darn expensive.
